Thermal Overload Relay
A thermal overload relay is a protective device used in electrical systems to monitor and protect electric motors from overheating due to excessive currents or prolonged operation. It works by measuring the motor’s current and …
Solid State Relay
A solid-state relay (SSR) is an electronic switching device that performs the same function as an electromagnetic relay, but without any moving parts. It uses semiconductor devices such as thyristors (SCRs), triacs, or transistors to …
Reed Relay
A reed relay is a type of electrical relay that utilizes reed switches as its switching mechanism. It combines the principles of a reed switch and a relay, providing the benefits of both components. Reed …
Reed Relay switch
A reed relay is a type of relay that uses reed switches as its switching elements. Reed switches are small, hermetically sealed glass tubes containing two ferromagnetic reeds with contacts at their ends. When a …
Electromagnetic Relay
An electromagnetic relay is a type of relay that uses an electromagnet to control the switching action. It consists of a coil, an armature, and a set of contacts. When a current flows through the …
Types of relay
Relays are electrical devices used to control the flow of current in a circuit. They are commonly used to switch high voltages or currents using a low-voltage control signal. There are several types of relays, …
earth fault relay
An earth fault relay, also known as an earth leakage relay or ground fault relay, is a protective device used in electrical systems to detect and respond to earth faults or ground faults. An earth …
surge protection device
A surge protection device (SPD), also known as a surge protector or surge suppressor, is a device designed to protect electrical and electronic equipment from voltage spikes or power surges. These surges can occur due …
